Answer: 20%

Step-by-step explanation:

Two bags contain marbles, while Bag A contains 112 marbles, bag B contains 140 marbles.

Number of marbles in bag A = 112

Number of marbles in bag B = 140

Differences in the marbles

= 140-112= 28

Percent fewer marbles in Bag A than Bag B will be:

Difference in marbles in the bags divided by the marbles in bag B multiplied by 100.

= 28/140 × 100

= 1/5 × 100

= 20%

finlep [7]

Answer:

The total weight of the metal bar in pounds is 25 pounds

Step-by-step explanation:

Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.

Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc

Mathematically;

60/100 * x = 15

60x = 15 * 100

60x = 1500

x = 1500/60

x = 25 pounds
